The instrumentation suite for the HBS-I
Bibliographic record
Abstract
High-Current Accelerator-driven Neutron Sources (HiCANS) are a promising new type of neutron sources, which can offer pulsed neutron beams with performance comparable to today’s existing research neutron sources. The Jülich Centre for Neutron Science JCNS at Forschungszentrum Jülich aims to realize a first HiCANS with the HBS-I neutron source featuring a proton beam energy of 20 MeV, a peak current of 100 mA, and a flexible frequency and duty cycle scheme. The HBS-I will allow to exploit the potential of these innovative neutron sources for a broad range of scientific and technological applications. The target station will be located in an experimental area on the campus in Jülich and host a suite of five instruments. A diffractometer, a small angle scattering instrument, and a neutron reflectometer address the most demanded scattering applications, while neutron imaging and prompt gamma neutron activation analysis cover the need of user communities such as engineering or cultural heritage research. This paper describes the preliminary layout of the HBS-I neutron source and the five instruments planned.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
